I just got them. I will be setting them up this weekend. They are very nice - black version. I will initially be using Denon POA-6600 monoblocks paired with the matching preamp, tuner and CD player. This is the setup as bought when new. I hear a lot about power requirements but the original owner said he bought the system new in this configuration and has had no issues. I will post pictures next week.
I am currently using a Sansui BA/CA 2000 amp/preamp paired with and Accuphase T-100 tuner and Sony ES CD player. Also Klipsch Lascala speakers upgraded with Bob Crites crossovers and tweeters. Sounds really awesome but I anticipate the K9's will sound better and I always wanted a pair.
